Title:
HIGH-TOUGHNESS MAGNESIUM-BASE ALLOY, DRIVE SYSTEM PART USING THE SAME, AND METHOD FOR MANUFACTURING HIGH-TOUGHNESS MAGNESIUM-BASE ALLOY MATERIAL
Document Type and Number:
Japanese Patent JP2006002184
Kind Code:
A
Abstract:

To provide a high-toughness magnesium-base alloy having excellent tensile strength, fracture elongation and fatigue strength at ordinary temperature and also having high heat-resistant strength characteristics at about 200°C.

The high-toughness magnesium-base alloy contains, by weight, 1 to 8% rare earth element and 1 to 6% calcium, and further, the maximum grain size of magnesium constituting a matrix is made to ≤30μm. The maximum grain size of an intermetallic compound 6 of at least either of the rare earth element and calcium is made to ≤20μm, and this intermetallic compound is dispersed in the grain boundaries 5 and grains 4 of the magnesium constituting the matrix.
